Please read! YouTube user Ciprianwiner wanted to know more about what I use to charge my sealed lead acid battery, so here it is.

The charger is a Numax 1 amp 12v sealed lead acid battery charger. I paid around £20 for it from a local battery specialist (Manbat) where as it would usually cost £35 on-line.

I am not saying that you never charge a sealed lead acid type with a car battery charger but I would advise being careful or using some sort of current limiting as once you have a gassing sealed battery from too much charging current its pretty much downhill from there in terms of capacity.

Usually you can find datasheets online from the battery manufacturers website with all of the charging specs for your specific battery.

Also it is common to see the battery’s voltage read well into the 13v range when it is taken off charge (I have even seen as high as 13.6v stay for a while!). But once you put a load on them it will come back down.

Hello friends, I am Pratyush Kumar and i am very happy to upload my this new video upon how can you charge your 9v dc battery and I request you all to subscribe my channel first and then watch the video. I’ll be to happy if you share my videos (which you like the most) on your social platform.

Charging my car battery with a 4 Amp battery charger.
The battery was not fully charged because I had been doing a lot of short distance stop and start driving, including some short distance driving at night.

I used a 4 Amp “Motogard” battery charger (made in New Zealand), which I purchased about 20 years ago.for around $30.

Showing some of the effects of too much voltage on your Car Battery.
Specifically Car Audio batteries. Check the manufacturer’s charging specs for max charging voltage before adding that Voltage Boost.

Today I’m going to show you how I’ve build a more complex 18650 battery charger. I got all the electronic components from banggood.com. I tested all the components before starting the project and they are all ok. The electronic parts cost 6.5 euros / battery.

If you connect a solar panel directly to a car battery, it will eventually overcharge the battery and damage it. That’s why you need to use a solar charge controller. This is my own design using the latest microcontroller and MOSFET circuitry. It consumes less than 1mA (that’s very little) and has a neat little blue LED that tells you the battery voltage. It can also be connected in various different configurations so you can do clever things like charge two batteries from one solar panel. You can get the PWM5 from www.256.co.uk

OnePlus 6 with Dash Charger is blazing fast, no doubt! Samsung’s adaptive fast charger is slower at the start, but the end result is not bad at all! The outgoing OnePlus flagship OnePlus 5T is surprisingly faster than OnePlus 6 at the beginning, but OP6 speeds up at the end! Watch the video and check yourself!
